Since the software is originally in Chinese, users often need to manually toggle the language: SSCOM V5.13.1 application. Locate the button labeled with Chinese characters
Check (if available) or manually control the RTS pin for direction switching. Sscom’s low latency makes it feasible for Modbus RTU testing.
Supports sending entire text or binary files directly through the serial line, which is useful for basic firmware updates or large data logging tests.
One of the most critical aspects of serial communication is matching the baud rate and other line parameters. Sscom V5.13.1 supports a broad range of baud rates, from 300 bps up to and even allows for custom values. This flexibility ensures compatibility with everything from legacy industrial equipment running at low speeds to modern high-speed UART (Universal Asynchronous Receiver-Transmitter) links.

Close other serial monitors (Arduino IDE, CuteCom). On Windows, check Device Manager → Ports (COM & LPT) for the actual number. Use mode command in cmd to list free ports.
. It is especially popular for testing embedded systems like Arduino, STM32, or ESP8266 because it allows for direct data exchange without a complex IDE. Key Features Portability

Relevant USB-to-Serial drivers (CH340, CP210x, FTDI, or PL2303) depending on your hardware interface. Storage: Less than 5 MB of free disk space. Getting Started (Step-by-Step)
For the rest of us—hobbyists tinkering with ESP32s, professionals validating RS-485 networks, or students learning microcontroller protocols— remains a timeless, underappreciated workhorse.
Data can be viewed in ASCII for text-based protocols or Hex mode for analyzing binary data frames, making it easier to diagnose communication issues. Since the software is originally in Chinese, users
SSCOM is a portable application and does not require a traditional installation.
: Reading raw data from industrial sensors and verifying response strings. Network Hardware : Configuring routers or switches via console ports.
| Capability | What It Does | Practical Benefits | |------------|--------------|--------------------| | | Assign individual settings (baud rate, parity, data bits, stop bits, flow control) for each open COM port. | No need to close one session to re‑configure another—perfect for testing devices with different protocols. | | Live Data Merging Window | Drag‑and‑drop any open port into a “merge window” where incoming bytes from all selected ports are displayed together, each prefixed with a configurable port identifier. | Instantly spot timing relationships, cross‑device communication patterns, or protocol collisions. | | Per‑Port Hex/ASCII Toggle | Switch any port’s view between pure ASCII, pure hexadecimal, or a split hex/ASCII mode. | Quickly decode human‑readable messages while still being able to inspect raw byte values. | | Real‑Time Logging with Timestamp Granularity | Enable logging per port or for the merged view. Each line can include: • Date + time (down to milliseconds) • Port ID • Direction flag (RX/TX) • Optional custom tag | Generates ready‑to‑import logs for Excel, MATLAB, or custom parsers. Millisecond timestamps are essential for debugging time‑critical embedded protocols. | | Dynamic File Capture & Replay | Capture traffic to a file on‑the‑fly (auto‑rotate when a size limit is reached). Later, load the capture and replay it on any selected port at original timing or at a user‑defined speed factor. | Perfect for regression testing: record a successful session once, then replay it repeatedly to verify firmware changes. | | Conditional Triggers & Auto‑Responses | Define simple trigger rules (e.g., “when the string ‘ERROR’ appears on COM3, send ‘RESET\r\n’ on COM5”). Supports regex patterns and multi‑byte binary sequences. | Automates repetitive diagnostic steps and reduces manual intervention during long‑run tests. | | Port‑Specific Macro Recorder | Record a sequence of keystrokes or command strings for a given port, save it as a macro, and bind it to a toolbar button or hotkey. | One‑click execution of complex command sequences (e.g., bootloader entry, firmware upgrade commands). | | Graphical Signal Analyzer (Optional Plug‑in) | For ports that carry binary waveform data (e.g., UART‑based sensor streams), the built‑in analyzer can plot voltage‑level equivalents, frequency spectra, or custom charts based on user‑defined parsing scripts (Python/JavaScript). | Turns raw serial data into visual insights without needing external oscilloscopes. | Supports sending entire text or binary files directly
